MDC self4j log4j ，mdc 设置的值无法打印出来，求问为什么？

Question

问题：
我的日志打印结果是这样的：
[main] INFO Test - 接口入参===

我想得到一个类似于这样的日志：f9e287fad9e84cff8b2c2f2ed92adbe6[main] INFO Test - 接口入参===

1.我的测试类
import org.apache.log4j.MDC;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Test {

static Logger logger = LoggerFactory.getLogger(Test.class);

public static void main(String[] args) {
    MDC.clear();
    MDC.put("logid", "f9e287fad9e84cff8b2c2f2ed92adbe6");
    MDC.put("merchant_id", 1);
    MDC.put("siteName", "北京");
    MDC.put("userName", "userwyh");

    MDC.put("mobile", "110");

    MDC.put("mchId", 12);
    MDC.put("mchName", "商户名称");

    logger.info("接口入参===");

}

2.我的log4j配置文件：
